Alfred Nobel’s fortune was based on his 1866 discovery that nitroglycerin, which is far too shock-sensitive to be transported or used safely, can be stabilized by adsorption onto a substance called kieselguhr to give what is familiar to us as dynamite. Nitroglycerin is the trinitrate of glycerol (1, 2, 3 - propanetriol). Write a structural formula or construct a molecular model of nitroglycerin.
